WATER-JET CONDENSER.

SPECIFICATION forming part of Letters Patent No. 456,828, dated July 28,1891.

Application filed April 3, 1891. Serial No. 387,538. (No model.)

To aZZ whom it may concern:

Be it known that l, ERNST KiiRTING, a subj ect of the King of Prussia,residing at Ilanover, Kingdom of Prussia, Germany, have invented new anduseful Improvements in WVater-Jet Condensers, whereof the following is aspecification.

My invention relates to condensers in which the condensation of steam isbrought about bya jet of water passing from a supply-nozzle through thesteam into a receiving-nozzle; and its object is to render the operativecapacity of the condenser variable without that the degree ofvacuum'produced by the condenser is materially influenced by suchvariation. For this purpose I make the receivingnozzle movablelengthwise and provide the same with a mechanism for shifting it, sothat the distance of its inlet end from the waterjet nozzle may bereduced or increased. By these means the operative length of thewaterjet, and consequently the extent of its surface, which acts as thesteam-condensing medium, may be varied in accordance with the quantityof steam to be condensed. Moreover, I combine with the said movablereceiving-nozzle a tubular channel to be called condens in g-tube,surrounding the former and having a plurality of passages or transverseslits distributed upon its length and serving to admit the steamthereinto, the receiving-nozzle operating relatively to the saidcondensing-tube as slide-valve to close the steam passages thereof insuccession in the measure as it is shifted toward the water-jet nozzle,and Vice versa. By the latter means the aggregate section of thesteam-currents and the surface of the condensingj et are always broughtinto the proper proportion to each other. The said passages or slits arepreferably arranged to form short channels inclined from their inlet endtoward the outlet end of the receivingnozzle.

The receiving-nozzle may be shifted by hand through the medium of alever, a rack and pinion, ascrew, or other suitable device, and if thecondenser is to be applied to a steamengine working with Varying powerthe nozzle may be so connected to the governor of the engine that itwill be shifted toward or away from the water-jet nozzle, according asthe power of the engine diminishes or increases.

If for starting the condenser an auxiliary jet of fluid induced underpressure should be required, it is advantageous to connect the valvecontrolling the admission of the said fluid with the mechanism foroperating the receiving-n ozzle in such manner that the valve will beopened when the receiving-nozzle is at or near the end of its instrokeand that the valve will be caused to closeimmediately after the nozzlehas commenced to be drawn outward.

In the annexed drawings, Figure l is a sectional view, and Fig. 2 theoutside elevation, of a water-jet condenser comprising my improvements.

e is the water-induction pipe; f, the steampipe; g, the watei eductionpipe; a, thewater-jet nozzle arranged to receive water from the pipe 6,and b the receiving-nozzle, which fits with its lower end in the pipe 9and is capable of sliding therein.

c is the condensing-tube fitting on the nozzle b and having the inclinedsteam passages or channels (Z distributed lengthwise upon the tube. Thenozzle 1) has at its lower end a cross-piece, to which is fixed the rodit, passing outward through a sleeve in the wall of pipe g, and wherebythe nozzle can be shifted. The rod h is connected to a hand-lever o,having 'a catch arranged to en gagewith the notches of a sector 13, inview of locking the lever in any desired position.

it is the nozzle for an auxiliary jet of fluid, the same being directedinto the nozzle a and forming the end of the supply-pipe q, while on isthe valve whereby the current of fluid in pipe q is controlled. The stemof this valve is connected by a lever and a rod r to the hand-lever 0,the said rod being paired with a pin in lever 0 by means of anelongatedeye '7', in order that the valve be opened only when the lever andnozzle 1) are near the upper end of their course.

I claim as my invention- 1. In a water-jet condenser, the combination,with the steam-pipe f, the water-induction pipe e, and thewater-eduction pipe g, of the water-jet nozzle (nfixed to pipe 6, thecon- (lensing-tube 0, having the steam-passages d,

the receiving-nozzle b, communicating with pipe 9 and movable lengthwisein the tube 0, and means for shifting the nozzle b, substantially asdescribed.

2. In a Water-jet condenser, the combination, with the steam-pipe f, theWater-induction pipe 6, and the water-eduction pipe g, of the Water-jetnozzle a, fixed to pipe 6, the receiving-nozzle b, communicating withpipe 1 and movable lengthwise, means for shifting the nozzle 1'), theauxiliary nozzle n, directed into nozzle a, the pipe q for supplying afluid to nozzle a, valve m, placed in pipe q, and a connection betweenthe said valve and the receiving-nozzle b,whereby the valve is openedwhen nozzle 1) is pushed toward the nozzle a, substantially asspecified.

In testimony thereof I have hereunto set my hand in the presence of twosubscribing Witnesses. I

ERNST KORTING.
